EYELETlNG-MACHINE.

SPECIFICATION forming part of Letters Patent N0.'369,246, dated August80, 1887.

A pplieation filed April 11, 1881.

To all whom it may concern.-

Be it known that Limes ALroRn House, a citizen of the United States,residing at Bridgeport, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements inEyeleting- Machines; and I do hereby declare the follow ing to be afull, clear, and exact description of the inveution,such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to certain new and useful improvements incorset-eyeleting machines, and has for its object to provide a machinewhich shall be strong and simple in its construction, which shall beadapted to feed'and set simultaneously the whole number of eyelets whichare necessary to be inserted along the rear edge of the corset-section,and which shall,furthermore,be so arranged that the section to beeyeleted must be in its proper position beneath the punches before themechanism for feeding and upsetting the eyelets can act; and with theseends in view my invention consists in the details of constructionhereinafter fully set forth, and then recited in the claims.

In order that those skilled in the art to which my invention appertainsmay more fully understand how to make and use myimproveinents, I willdescribe the same in detail, refer ring by figures of reference to theaccompanying drawings, which form a partof this specification, and inwhich Figure 1 is a front elevation of my machine, the work-table beingremoved; Fig. 2, arear elevation; Fig. 3, an end elevation; Fig. 4, a,vertical section taken at theline w a: of Fig. 1; Fig. 5, a sectiontaken at the line 3, y of Fig. 3, showing the feedingplate in plan View.In this figure the feed-box is omitted. Fig. 6 is a detail section ofthe clutch mechanism.

Similar figures of reference indicate like parts in all the figures ofthe drawings.

1 is the vertical frame of the machine; 2, a horizontal. tablefrom whichthe frame extends, and 3 are suitable legs upon which the table andframe aforesaid are upheld.

4 are journal-blocks mounted upon the table 2. 5 is the main shaft,which turns in said journals, and 6 is the driving-pulley, whereby saidshaft is rotated. Secured upon Serial No. 234,335. (No model.)

and earriedby shaft 5 are a switch-cam, 7, and a clutch, 8, whosefunctions will be heroinafter more fully explained.

9 is a gear having at either end thereof and fast thereto the clutch 10and collar 11,1espectively. The gear, clutch, and collar are journaledon shaft 6, which revolves within them, exceptas will be presently setforth.

12 is an abutment-collar secu red on and car ried by the shaftaforesaid.

13 is the pitman-shaft, journaled near its ends in bearings 14 on thetable. This shaft has two pairs of cranks or eccentrics formedthereonviz., a pairnumbered 15 at its ends, outside the bearings 14, andanother pair, 16, inside the said bearings. The eccentrics 15 and 16 areset at one hundred and eighty degrees to each other, as may be seen byreference to Fig. 1.

17 are pitmen connected at one end to cranks 15, and at the other end towrists 18, formed on a sliding bar, 19, which latter is adapted to beactuated vertically through the pitmen last aforesaid.

20 are eyelet-punches which project downwardly from the bar 19, andwhich are preferably adapted for removal and adjustment.

21 are other pitmen connected to eccentrics 16, and also to the bottomof another verticallysliding bar, 22, which is arranged in ways in theframe, and which has upon its top edge a series of flanging-dies, 23,corresponding to the punches on the upper bar. The arrangement of theeccentrics and pitmen aforesaid is such as to draw the bars toward eachother at each revolution of the shaft 13, and then to return them totheir normal position, which is as shown at Fig. 1.

24 is a gear-wheel secured upon and carried by shaft 13. Its teeth meshwith the teeth of the smaller gear, 9, which imparts rotation thereto atcertain times, as will hereinafterbe fully setforth.

25 is a disk journaled on the shaft 13 and carried by friction with gear2i. It is not so tight against the latter, however, but that it may bemoved independent thereof. Said disk has upon its outer face a wedge,26. (See Figs. 1 and 4.)

27 is a cam secured upon the gear 13 at the side opposite to thefriction disk last described.

ICC

28 is a foot-lever pivoted beneath the machine, and 29 is a pawlextendingfrom the end of said lever upward and restingits end againstthe friction-disk, as seen at Fig. 4.

30 is a pivoted bell-crank lever whose upwardly-extending arm is yokedat 47. The yoke engages collar 11, and is adapted, when the lower arm ofthelever is depressed,to move the said collar and the gear and clutchlengthwise of the shaft 5. At the rear of the machine is arrangedthefeeding-plate 31,having formed therein guideways 32, through whichthe eyelets are fed from the feed-box 33 at the top of the plate to thepunches. Springs 34 prevent the eyelets from slipping out of theguideways by gravity, but they are not sufficiently powerful to preventthe said eyelets being readily withdrawn from their grasp. Thefeedingplate and feed-box are hinged upon brackets 35, which rest uponknife-edges 36 at the top of the frame, (see Figs. 2 and 4,) and theplate and box are further supported and also receive a backward rockingmovement on the knife-edges from arod, 36, whose wheel 37 rests on theperiphery of cam 27, and the said rod is steadied by a pivoted brace,38, which extends from the wheel to the table, as seen at Fig. 4.

39 is a lever pivoted at its center to a bracket, 40, on the frame, andextending from the sliding bottom 41 of the feed-box to the switch-cam7, which, through ashoe or roll, serves to oscillate said lever on itspivotal point, and thereby to reciprocate the bottom of the feed-boxacross the top ends of the eyelet channels or guideways,so that eyeletsare constantly introduced therein.

42 is the work-supporting table, pivoted at 43 to the frame and adaptedto be turned on its pivotal point upward to bring the work into properposition relative to the punches. Upon said work-tableis superposed abindingstrip, and between said table and strip the corset is drawn, soas to be tightly held while being operated upon.

44 are swinging stops secured on the short shaft 48, and against thesestops the extensions 45 on the table abut when in the position shown atFig. 4. A rod, 46, secured through a short arm to shaft 48, connects thelatter to the foot-lever 28. The effect of this connection is to preventany movement of the said foot-lever while the table is engaging saidstops.

The operation of myinvention is as follows: The corset-section is placedin position on the work-table by drawing it longitudinally beneath thebinding-strip, (see Fig. 5,) and the table is then turned from itsnormal position, Fig. 4, upward to bring the work between the punchesand the dies. This movement of the table frees the stops 44 and the rod,so that the treadle 28 may be depressed by the foot of the operator.When the work is in position, as aforesaid, the treadle 28 is firstdepressed. The wedge 26, when the machine is at rest, is interposedbetween the disk, of which it forms gear 9, gear 24 is caused to turn.

a part, and the yoked portion of the bellcrank lever, and the end of thepawl 29 rests against the surface of the disk directly beneath thewedge. The wedge is therefore an obstacle to any sliding movement of thegear 9 and its collar and clutch on theshaft. The depression of thefoot-lever 28 through the pawl 29, which engages the wedge, rotates thedisk independent of the gear 24, and raises the wedge out of the path ofthe yoke on the bell-crank, so that the latter is free upon pressureapplied to lever 30 to slide the gear 9 and its clutch and collar alongthe shaft. \Vhen so moved, the clutch 10 engages clutch 3, which isconstantly revolving with the shaft, and thereby, through The rotationof the shaft 13, effected by the gear last referred to, draws the bars19 22 together and sets the eyelets firmly in.the corset-section, aswill presently more fullyappear. When the gear 24 starts,it carries withit by friction the disk 25, and when the former has completed one turnthe wedge 26 on the latter forces itself behind the yoke of thebell-crank,withdraws the clutch 10 out of engagement with the clutch 8,and the machine stops. The arrangement described-viz., the use of twolevers, both of which must be depressed-is adopted sothat accidentalstarting may be rendered improbable, and the abutment of the worktableagainst the stops which connect withlever 28 is thought necessary sothat the ma chine cannot be set in motion unless the work is in properposition between the punches. These features are found to secure greatuniformity of the finished work,since it would be difficult to run themachine in any but the right way. The feed -plate, which has thechannels for the proper slide of the eyelets, has the feedbox mounted atits upper end, and the reciprocation of the bottom of the said box, uponwhich the eyelets lie, constantly carries said eyelets back and forthbefore the openings of the channels, so that the latter are constantlykept filled. The position of the plate when the punches first commencetheir descent is such that the end eyelet of each channel is taken onthe point of one of the punches, which then pierce the fabric of thecorset'section. Vere it not for the rocking movement now imparted to thefeedingplate the said plate would be caught between the dies and theenlarged top portion of the punches. At this time, however, after thepunches have pierced the goods, and before the eyelets have beenflanged, the cam-surface 27 raises the rod 36, and the plate is rockedback on its pivotal point out of the way of the punches. As it recedes,the eyelets which have been taken on the punches are drawn from thegrasp of the springs, and new eyelets slide by gravity into properposition at the ends of the channels. As the punches and dies cometogether, the eyelets are properly flanged and compressed, as inordinary machines for setting eyelets. When the punches have againreceded, the plate returns by gravity to its normal posit-ion. When thetable has been turned upward to present the work to the punches and thelever 28 has been depressed, the shaft 48 turns on its axis, and thestops look the table in its upturned position till, by the raising ofthe foot-lever, the shaft 48 and the stops are rotated back to theposition in which they are shown at Fig. 4., and the table therebyreleased.
